Results are presented from an allocation study in a determination on the appropriate number of Idaho State Police patrol officers needed to patrol the Federal and State highway systems of Idaho 24 hours a day.
Abstract
Data were broken into three different levels based on crashes, average traffic, and calls for service per milepost in Idaho. Tier 1 roads are areas of the State where there are high amounts of traffic, crashes, and other calls for services, most times of the day. Tier 1 roads need to have a trooper pass by every 4 to 6 hours to promote maximum prevention; therefore a minimum of 4 times a day, a maximum of 6. Tier 2 roads are areas that are busy only at certain times of the day and have less traffic volume, crashes, and other calls for service. Tier 2 roads need to have a trooper pass by each milepost every 8 to 12 hours; a minimum of 2 times per day and a maximum of 3. Tier 3 roads have less traffic, few crashes or other calls for service, and need to be traveled once per 24 hours by troopers. The average response time for Idaho State Police (ISP) calls for service that are not officer initiated is currently over 18 minutes. It was estimated, using a Police Allocation Manual formula that the ISP will need to hire 88 additional troopers to meet the demands. Total trooper allocation for the State would then reach 231, up from the current 143. These are results from an initial study in a determination of the number of ISP patrol officers needed to allow for proactive patrolling on rotating 24 hour shifts on all Idaho State interstates and highways.
